Nonparametric Instrumental Variable Regression through Stochastic Approximate Gradients

no code implementations8 Feb 2024 Caio Peixoto, Yuri Saporito, Yuri Fonseca

This paper proposes SAGD-IV, a novel framework for conducting nonparametric instrumental variable (NPIV) regression by employing stochastic approximate gradients to minimize the projected populational risk.

Price formation in financial markets: a game-theoretic perspective

no code implementations23 Feb 2022 David Evangelista, Yuri Saporito, Yuri Thamsten

We propose two novel frameworks to study the price formation of an asset negotiated in an order book.

KrigHedge: Gaussian Process Surrogates for Delta Hedging

1 code implementation16 Oct 2020 Mike Ludkovski, Yuri Saporito

We further discuss the application to Delta hedging, including a new Lemma that relates quality of the Delta approximation to discrete-time hedging loss.

Extensions of the Deep Galerkin Method

no code implementations30 Nov 2019 Ali Al-Aradi, Adolfo Correia, Danilo de Frietas Naiff, Gabriel Jardim, Yuri Saporito

We extend the DGM algorithm to solve for the value function and the optimal control \simultaneously by characterizing both as deep neural networks.

Solving Nonlinear and High-Dimensional Partial Differential Equations via Deep Learning

2 code implementations21 Nov 2018 Ali Al-Aradi, Adolfo Correia, Danilo Naiff, Gabriel Jardim, Yuri Saporito

In this work we apply the Deep Galerkin Method (DGM) described in Sirignano and Spiliopoulos (2018) to solve a number of partial differential equations that arise in quantitative finance applications including option pricing, optimal execution, mean field games, etc.
